Waste Lithium Battery and Waste Circuit Board Recycling and Processing Equipment

Background：

  * Lithium-ion battery classification: soft-shell lithium-ion batteries, hard-shell lithium-ion batteries, 

     cylindrical lithium-ion batteries, positive and negative electrode sheets, etc.

  * Lithium-ion batteries mainly consist of a casing, positive electrode, negative electrode, electrolyte, 

     and separator：

     - The positive electrode sheet is formed by coating lithium cobalt oxide powder onto both sides of 

        an aluminum foil current collector using PVDF.

     - The negative electrode sheet has a similar structure to the positive electrode, consisting of carbon 

        powder bonded to both sides of a copper foil current collector.

Waste Lithium-ion Battery Crushing / Pyrolysis / Sorting Recycling 

Production Line：

  A. Process Principle: Physical crushing/pyrolysis/sorting process to obtain copper, aluminum, and black 

       powder (graphite powder, lithium iron phosphate, lithium cobalt oxide, etc.)

  B. Processing Capacity: 100 ~ 2,000 Kg/Hr, recycling rate over 90%

  C. Basic Equipment: Single-shaft shredder, hammer crusher, magnetic separator, pulverizer, baffle 

       separator, black powder separator, airflow separator

  D. Optional Equipment: Carbonization furnace (pyrolysis furnace) 

  E. Air Pollution Control Equipment: Pulse dust collector and other flue gas treatment equipment

      (Option)

Waste Lithium Battery Crushing/Pyrolysis/Sorting Recycling Production Line - 

Process Flow Description :

  A. After discharge, lithium batteries are conveyed into the crushing equipment for crushing.

  B. After crushing, they enter the pyrolysis furnace for further decomposition.

  C. The pyrolyzed material enters the screening system.

  D. The screening/crushing/re-screening system further crushes/re-screens the stripped black powder, 

       separating it into ① black powder (graphite powder, lithium iron phosphate, lithium cobalt oxide, 

       etc.) and a copper-aluminum mixture.

  E. The copper-aluminum mixture is then separated into ② copper and ③ aluminum by airflow 

       screening.
